问题
I can't seem to include glu.h in my Android NDK project.
I'm trying to port existing C++ code to NDK, and it uses glu in a few places (notably gluErrorString).
Does OpenGLES not have glu?
Is there a port I can use?
If not I can probably remove the calls to things like gluPerspective and so on, but what do I do about gluErrorString?

Does OpenGL ES not have glu?
No, it doesn't. Look at this: Platform OpenGL Includes collection. Under Android there are only the following headers:
OpenGL ES 1.1:
#include <GLES/gl.h>
#include <GLES/glext.h>
OpenGL ES 2.0:
#include <GLES2/gl2.h>
#include <GLES2/gl2ext.h>
Is there a port I can use?
Yes, there is a partial port of GLU for Android - GLU ES (it supports gluErrorString, gluPerspective and numerous other functions):
GLU 1.3 partitial port (libutil and libtess components only) for OpenGL ES 1.x (CM - Common profile) and above.
This port supports:
- Quadrics: gluNewQuadric(), gluDeleteQuadric(), gluQuadricCallback(), gluQuadricNormals(), gluQuadricTexture(), gluQuadricOrientation(), gluQuadricDrawStyle(), gluCylinder(), gluDisk(), gluPartialDisk(), gluSphere().
- Registry: gluGetString(), gluCheckExtension(), gluErrorString().
- Projection matrix manipulation: gluOrtho2D(), gluPerspective(), gluLookAt(), gluProject(), gluUnProject(), gluUnProject4(), gluPickMatrix(). 2D Mipmaps: gluScaleImage(), gluBuild2DMipmapLevels(), gluBuild2DMipmaps().
- Tesselation: gluBeginPolygon(), gluDeleteTess(), gluEndPolygon(), gluGetTessProperty(), gluNewTess(), gluNextContour(), gluTessBeginContour(), gluTessBeginPolygon(), gluTessCallback(), gluTessEndContour(), gluTessEndPolygon(), gluTessNormal(), gluTessProperty(), gluTessVertex().
